"The reason I say it could be a 'genius' idea is that - for the first time - someone has come up with a way to have as many freakin' Turtles as they want," Laird wrote. "I mean, if the TMNT are actually members of an alien race, there could be a whole PLANET of them!"

Teenage Mutant Ninja Turtles - which is produced by Bay and directed by Jonathan Liebesman - will open in US cinemas on December 25, 2013.
